The purpose of this application, under Article 55.3.1 of the Code, is to remove the homonymy between two family-group names of Hexapoda: the coleopteran tribal name AcalyptiniThomson, 1859 (type genus AcalyptusSchönherr, 1833; family Curculionidae) and the heteropteran tribal name AcalyptiniBlatchley, 1926 (type genus AcalyptaWestwood, 1840; family Tingidae). We propose to adopt the entire type genus name AcalyptaWestwood, 1840 as the stem for the corresponding family-group name AcalyptainiBlatchley, 1926. The senior homonym AcalyptiniThomson, 1859 (Coleoptera), based on AcalyptusSchönherr, 1833, will remain unchanged.
